V úvodní části je popsána definice architektonického betonu a také výhody a nevýhody jeho realizace. V dalších kapitolách jsou uvedeny charakteristiky, dávkování či chemické složení vstupních materiálů. Kromě návrhu receptury je důležitým parametrem pro vytvoření kvalitního povrchu betonu zhutňování, precizní uložení do bednění a následné ošetřování povrchu. Popsány jsou také jednotlivé druhy architektonických betonů, jejich způsob vyrábění s uvedenými příklady na konkrétních realizovaných stavbách. V praktické části byly navrženy 4 receptury, kde se měnil druh nebo dávkování vstupních surovin.

Abstract This diploma thesis focuses on the influence of properties of feedstocks for the production of quality surfaces of architectural concrete. The introductory part describes the definition of architectural concrete with the advantages and disadvantages of its implementation. In the following chapters, the characteristics, the dosage or the chemical composition of the input materials are given. Besides the design of the mixture, important parameters for the creation of a quality surface of concrete are compaction, precise placement in formwork and subsequent treatment of the surface.

  • Color Hardener
    COLOR HARDENER Super Stone® Color Hardener is an aggregate powder that allows concrete contractors to create durable vibrant decorative concrete projects. Using a mixture of light-fast color pigments, hard mineral aggregates, and Portland cement, this product creates a surface that is more wear resistant and less permeable to moisture and de-icing chemicals more so than standard concrete. Super Stone® Color Hardeners produce a more intense coloration than integral colors because of its concentration of color on the surface of the concrete. RECOMMENDED USAGE ADVANTAGES For use on newly poured concrete surfaces • Durable & Wear Resistant where color and durability are specified for stamp • Resistant to freezing & scaling due to de-icing impressions or smooth polished surfaces. Super salt/chemicals. Stone® Color Hardener may be applied for indoor or outdoor use. • Builds in color & strength eliminating the cost of periodic painting of surface. COVERAGE 60 lb Bucket of Light Colors with 2-3 Applications Cover Approximately 60-80 ft2 60 lb Bucket of Dark Colors with 2 Applications Cover Approximately 80-120 ft2 SURFACE PREPARATION Use of Super Stone® Color Hardener primarily takes place with the proper attention to the sub-grade preparation and concrete mix. The sub-grade should be graded uniformly, well drained, and have sufficient load-bearing characteristics to prevent cracking. The concrete mix should contain a minimum of 5½ sacks of cement per cubic yard which is 517lbs per 300 kg/m³ of concrete. Fine and coarse aggregates should be free of deleterious (reactive) particles and the water content should be held to minimal practical amounts.

  • Concrete Masonry
    110401545 Building Construction 11 – Concrete Masonry Dr. Omar Al Hattamleh Department of Civil Engineering Hashemite University Concrete Masonry Units (CMUs) • Precast Concrete Masonry Blocks: Manufactured by vibrating a stiff concrete mixture into metal molds, immediately turning it out wet onto a rack (so that the mold can be reused immediately) at a rate of 1000 or more units per hour – • Racks are cured at an accelerated rate by subjecting them to steam, either at the atmospheric pressure or for faster curing at higher pressure. After the units are steam cured, the units are dried to a specific moisture content, and bundled in wooded crates for shipping to the construction site ١ Concrete Masonry Units (CMUs) • Steam curing in autoclaves accelerates curing Concrete Masonry Units (CMUs) III • Made in varying sizes and shapes: – Standard hollow blocks Standard nominal size: 8" x 8" x 16" – Actual size is 3/8-inch less in each dimension. ٢ Concrete Masonry Units (CMUs) IV • Can be manufactured in a great variety of shapes and sizes CMU Weight Classifications • Lighter weight blocks – Less expensive to transport and lay – Lower thermal conductivity: higher fire-resistance rating and potentially better building envelope thermal performance • Heavier weight blocks – More durable – Higher compressive strength – Better acoustical isolation between adjacent spaces ٣ Concrete Masonry • Concrete Masonry Dimensions – Like brick masonry walls, concrete block wall dimensions should conform to the dimensional module of the block, in this case 8 inches. This minimizes the need to cut block or work with small pieces. Laying CMU I • Mortar is identical to that used for brick masonry.

  • Properties of High-Performance Concrete Containing High Reactivity Metakaolin
    SP-228—21 Properties of High-Performance Concrete Containing High Reactivity Metakaolin by A. Bonakdar, M. Bakhshi, and M. Ghalibafian Synopsis: High Reactivity Metakaolin (HRM) is an engineered pozzolanic mineral admixture, reacting aggressively with calcium hydroxide which results in significant performance of concrete. HRM has been introduced to be a beneficial alternative for silica fume, required in the formulation of high strength/performance concrete. In this study, different aspects of concrete mechanical behaviors have been studied including compressive, flexural and splitting tensile strengths. Also some characteristics of concrete durability were investigated including water absorption, water penetration and gas permeability. In mixture proportioning, 5%, 10% and 15% of cement content is replaced by HRM or silica fume for comparative study. It was observed that both concrete with HRM and silica fume would perform almost the same in improving the mechanical properties of the materials. However in the case of workability and durability, a better performance was obtained in concrete with HRM. It was concluded from the investigation that HRM could be an appropriate substitute for silica fume in producing high performance concrete. Keywords: durability; gas permeability; high-performance concrete; Metakaolin; silica fume 287 288 Bonakdar et al. Mehdi Ghalibafian is an associate professor of Civil Engineering at the University of Tehran, Iran. He received his BS and MS from the University of Tehran, Iran and his PhD (1965) from Sorbonne University, Paris, France. His research interests include construction materials, reinforced concrete structures, steel structures and rehabilitation of old structures.
